That helm cache is stored in a hash-table, AFAIU, in which case we
should have seen that in the GC report.  But in all of the cases where
people complained about such huge RSS, the GC report shows a very
small Lisp memory usage, so that helm cache cannot be the culprit.
It's something else, whether related to helm-ff-keep-cached-candidates
or some other feature.
